Titanium Dioxide Nanoparticles and Cetylpyridinium Chloride Enriched Glass-Ionomer Restorative Cement: A Comparative Study Assessing Compressive Strength and Antibacterial Activity.

Objective: To evaluate the addition of titanium dioxide (TiO) nanoparticles and cetylpyridinium chloride (CPC) on the compressive strength and antibacterial activity of conventional glass-ionomer cement (GIC).

Study Design: TiO nanoparticles enriched GIC was prepared by adding 3% TiO nanoparticles (w/w) into the powder component of conventional GIC. CPC containing GIC was developed by incorporating 1% CPC (w/w) into conventional GIC powder.

Peripapillary Retinal Nerve Fiber Layer (RNFL) Thickness Measurements by Topcon SD-OCT in Myopic Patients.

Objective: To evaluate the effect of low-to-moderate myopia on peripapillary retinal nerve fiber layer (RNFL) thickness measured by Topcon SD optical coherence tomography (OCT).

Study Design: Cross-sectional study.

Place And Duration Of Study: Ophthalmology Department, Shifa Foundation Falahee Clinic, over a period of one year starting from June 2015.
